Description
- The present invention relates to a transportation means used for transporting or carrying luggage and more particularly pertains to a luggage trolley people use in their daily life, work, business trips and travels.
- Luggage trolleys are very common transportation means. As luggage trolleys are relatively large in size and occupy a larger space, they bring great inconvenience to people who are going on a trip. To reduce the space occupied during storage, luggage trolleys are usually collapsible and foldable. A conventional luggage trolley mainly comprises a baseboard used for receiving luggage articles and a pull handle used for pushing and pulling the trolley body. The baseboard of the luggage trolley is disposed with a wheel on each of the two sides thereof, and a supporting leg at the underside thereof. One of the peripheries of the baseboard is fixedly or removably connected to the pull handle. The supporting leg of this kind of luggage trolleys is usually engaged with a corresponding opening of the baseboard by insertion or fixation or fixed on the periphery of the baseboard by welding. The supporting leg and the wheels therefore constitute three supporting points of a luggage trolley. This increases the difficulty in reducing the size of the luggage trolley during storage. Moreover, during transportation of bulky articles, the transported articles have to lean against the pull handle to achieve a relatively secure support. If the road is rugged, the transported articles may easily slip off and get dirty and damaged.
- In view of the aforesaid disadvantages now present in the prior art, the object of the present invention is to provide a light luggage trolley which is simple to use, convenient to carry, occupies a small space during storage and transports articles securely.
- To attain this, the present invention generally comprises a baseboard, a pull handle and running wheels. The running wheels are respectively rotatably fixed at two ends of an axle disposed at an underside of the baseboard near a first baseboard periphery thereof. The pull handle is fixed on the first baseboard periphery, and its extending direction and a running direction of the running wheels are in a same plane surface. A foldable board is pivotably connected to a second baseboard periphery opposite to the first baseboard periphery. A supporting axis which is parallel to the axle is disposed at an underside of the foldable board. A movable supporting stand is rotationally fixed on the supporting axis. One end of a spiral spring is fixed on the supporting axis, and an opposite end thereof is fixed on a hook disposed on the movable supporting stand at a predetermined distance from the supporting axis. One end of the movable supporting stand near the supporting axis is disposed with a stopper which stops further rotation of the foldable board by pressing against the underside of the foldable board when the movable supporting stand rotates around the supporting axis to become perpendicular to a board surface of the foldable board.
- Preferably, the underside of the baseboard of the present invention is disposed with a plunger latch. A keyhole which allows insertion and/or withdrawal of the plunger latch is disposed at the underside of the foldable board at a position corresponding to the position of the plunger latch.
- By disposing at the underside of the foldable board a movable supporting stand which can be perpendicular or parallel to the plane surface of the foldable board, the movable supporting stand can provide effective support to the foldable board during use. The movable supporting stand can also be folded to the plane surface of the foldable board during storage so as to effectively reduce the space the present invention occupies. Moreover, disposing a locking mechanism comprising a plunger latch and a keyhole between the baseboard and the foldable board of the present invention can help keep the baseboard and the foldable board in a same plane surface and thereby providing a secure supporting platform for the transported articles.

FIGS. 1 to 4 illustrate the construction of the present invention from different projection angles and its related member. - The luggage trolley A comprises a
baseboard 1, a pull handle 2 and runningwheels 3. - The
baseboard 1 is a rectangular stiff board. The twowheels running wheels 3 are respectively fixed at two ends of anaxle 102 disposed at an underside of thebaseboard 1 near afirst baseboard periphery 101 thereof. Each of the twowheels axle 102. - The pull handle 2 comprises two parallel
long rods extension member 106 extended from thefirst baseboard periphery 101 of the baseboard, and the other end disposed with ahandle 203 which connects the twolong rods extension member 106 extends towards the same direction as the twolong rods baseboard 1. The longitudinal direction or the extending direction of the twolong rods wheels long rods wheels handle 203 while an obtuse angle is formed when the luggage trolley A is being pushed through thehandle 203. In order to reduce the size of the luggage trolley A, each of the twolong rods handle 204. - A
foldable board 4 is connected pivotably to asecond baseboard periphery 103 opposite to thefirst baseboard periphery 101. Thesecond baseboard periphery 103 is parallel to theaxle 102. In this way, thefoldable board 4 can rotate around thepivots 104 disposed on thesecond baseboard periphery 103 so that thefoldable board 4 can be folded to lie on thebaseboard 1 or become perpendicular to thebaseboard 1. The underside of thefoldable board 4 is disposed with a supportingaxis 401 which is parallel to theaxle 102. A movable supportingstand 5 is fixed on the supportingaxis 401 and can rotate around the supportingaxis 401. One end of aspiral spring 501 is fixed on the supportingaxis 401, and an opposite end thereof is fixed on ahook 502. Thehook 502 is fixedly disposed on the inner frame of the movable supporting stand 5 (refer toFIGS. 4 a and 4 b) at a predetermined distance from the supportingaxis 401. Thespiral spring 501 hanging between the supportingaxis 401 and thehook 502 is usually tensed so that the movable supportingstand 5 is maintained at a relatively fixed angular phase position relative to the supportingaxis 401. One end of the movable supportingstand 5 near the supportingaxis 401 is disposed with astopper 503. Thestopper 503 can be part of the movable supportingstand 5. When the movable supportingstand 5 rotates around the supportingaxis 401 to become perpendicular to the board surface of thefoldable board 4, thestopper 503 presses against the underside of thefoldable board 4 to stop further rotation of the movable supporting stand 5 (refer toFIG. 2 ). Therefore, the pulling force exerted on the movable supportingstand 5 by thespiral spring 501 through thehook 502 which makes the movable supportingstand 5 deviate from the direction perpendicular to the board surface of thefoldable board 4 is neutralized by the pressure between thestopper 503 and the underside of thefoldable board 4, thereby securing the movable supportingstand 5 on a direction perpendicular to the board surface of thefoldable board 4. At the same time, the pressure between thestopper 503 and the underside of thefoldable board 4 can further provide support to thefoldable board 4 for receiving luggage. - The underside of the
baseboard 1 near thesecond baseboard periphery 103 is disposed with aplunger latch 105. Theplunger latch 105 is a curved hook which can rotate or turn around a direction perpendicular to thebaseboard 1. Akeyhole 402 which allows insertion or withdrawal of theplunger latch 105 is disposed at the underside of thefoldable board 4 near thesecond baseboard periphery 103 at a position corresponding to the position of theplunger latch 105. When the luggage trolley A is in use, theplunger latch 105 of the baseboard is inserted into thekeyhole 402 of the foldable board so as to fix thebaseboard 1 and thefoldable board 4 in the same plane surface so that luggage can be disposed on the upper surfaces of thebaseboard 1 and thefoldable board 4. - To use the luggage trolley A, first lower the
foldable board 4 until it is in the same plane surface as thebaseboard 1. Then, insert theplunger latch 105 of the baseboard into thekeyhole 402 of the foldable board to fix thefoldable board 4. The luggage trolley A is then ready for use (refer toFIGS. 1 and 3 ). To store the luggage trolley A disposed with transported articles, pull out the movable supportingstand 5 around the supportingaxis 401 so that it becomes perpendicular to the board surface of thefoldable board 4. In this way, the movable supportingstand 5 remains upright as thestopper 503 presses against the underside of the foldable board 4 (FIG. 2 only shows that the movable supportingstand 5 is perpendicular to the board surface of thefoldable board 4; refer to status shown inFIGS. 1 and 3 for the position relation of thefoldable board 4 and the baseboard 1), and the luggage trolley A is securely supported by three supporting points, namely the twowheels stand 5.
